DIGITISE

Purpose

Digitise curves.

Syntax

Description

This command allows the user to input data points for selected curves by using a digitising tablet attached to the host computer. Orthogonal curves may be digitised in their respective view and the Stem and Stern Profile curves may be digitised in Buttock view.

The first time the command is issued for a given line set the user must supply two coordinates which define the diagonal of the Window Box in which the digitisation is to take place, these will be used to offset and scale the input data. The user will then be prompted to pick the 4 corners of the drawing area. 4 points are necessary in order to calculate correct alignment.

Having defined the digitising window the user can then digitise the selected curve. The user selects points using the First button on the mouse/pen (or SPACEBAR on the keyboard) and the selects CANCEL CURSOR (or any other Button or Key) to terminate digitising for the curve. The curve becomes CURRENT and can be manipulated using the normal techniques. Subsequent curves of the same line-set can then be digitised without re-defining the window.
